To all whom it may concern:

Be it known that I, CHAnLEs F. Nroms'r, a citizen of the United States, residing at Bucyrus, in thecounty of Crawford, State of Ohio, have invented certain new and useful Improvements iii-Devices. for Locating Sunken Vessels and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will en able others skilled in the art to which: it appertains tomake and use the same.

Thejpresent invention is directed to improvements in devices for locating disabled. submarine vessels, and has for its object to provide a device of this character which can be released by the crew, whereby the position of the sunken vessel can be ascertained.

A further object of the invention is to provide a device of this character which when released .upon sinking or disabling of thevessel, can be distinguished upon the surface of the water, and further to provide a device so constructed as to be seen at day or night.

A still further object of the invention is to provide a device of this character which will permit a rescue crew to carry on a conversation with the crew of the sunken vessel.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a fragmentary sectional view of a vessel, showing the device released. Fig. 2 is a sectional view on line 2-'-2 of Fig. 1. Fig. 3 is a sectional View on line 3-3 of Fig. 2. Fig. 4 is a detail sectional view through the float.

Referring tovthe drawing 1 designates a of which is. mounted a pair of spaced bearings 2, which rotatably support the shaft 3. 4 Slid on the shaft is. a drum 4, which has wound thereon an electric conasses through the box 6, said stu ng box being attached to the deck of the vessel and is alined with the opening 7 formed in the bottom of the holder 8, which is supported by the deck of the vessel, whereby said cable can be attached to the coupling 9. The coupling 9 is connected to the float 10, in which is located a telephone 11, and the incandescent lamps 12, said lamps being arranged ad,-

ducting cable 5, which Specification of Letters Patent. Patented June 20 1916, AppliationfiledFebruary 1, 1916. Serial No. 75,598,

jacent the bulls eyes 13, which may be of any. suitable colored glass.

The shaft '3 is provided Which has opening thereinto a lateral bore 15, and through which the. cable 5 enters so .as to lie in the bore 14. The cable is with a bore 14,

attached to the socket 16, said socket being mounted in the outer end of the bore 14. Detachably connected to the socket 16 is a plug 17, which has leading therefrom circuit wires 18, said wires being incirouitwith the batteries 19 and telephone 20, which are "suitably mounted on the vessel.'. Thus it will be seen thatwhen the plug 17 is engaged in the socket 16, that the circuit through the wires 18 and cable 15 is closed, thereby lighting the lamps and' placing the telephone 11 in circuit with the telephone .20. The float is provided with a closure 21, which can' be removed by the rescue crew so that access may be had to the telephone 20 23, said pawl serving to prevent rotation of the shaft 3, until the pawl has been actuated to disengage the ratchet wheel. The

shaft 3 has fixed to the end adjacent the ratchet wheel a crank handle 24, which.

servgs to wind the cable 5' upon the drum 4. y the shaft 3, the same can move longitudinally slidably mounting the drum 4 upon of said shaft when the float is rising, the

cable meanwhile unwinding from the drum, whereby there will be a direct line of cable from the drum to the stuflingbox 6.

From the foregoing description it will be seen that should a vessel become disabled so as tonot be able to rise to the surface under its own power, that the float 10 can be released so that same can rise to the surface to indicate the position of the disabled vessel. To release the float, it is only necessary to rock the pawl 23 by placing the foot upon the extension 25 thereof, whereby .the ratchet wheel will be released so as to permit the drum to rotate as the float rises. It will'be of course understood that the plug 17- is inserted in the socket after the float has reached the surface.

When it is desired tame the device for locating sunken vessels, other than submarines, it is not necessary to equip the float is Wound upon the drum in a reverse direction so that the pawl will act as a brake to prevent too rapid unwinding of the cable. It will be of course understood that the electric cables can be incased in lead so as to prevent corrosion.

What is claimed is A signal for submarine vessels comprising a holder mounted on the deck thereof, a float normally engaged in the holder, a shaft journaled Within the vessel, a drum slidable on the shaft and rotatable therewith, an electric cable windable on the drum and having one end attached to the float, -a socket formed in one end of the shaft, the other end of said cable entering said soelreh means carried by the shaft for holding the same against rotation, whereby the float is positively held in the holder, incandescent lamps and a telephone mounted in the float, batteries and a telephone mounted in the vessel, a plug insertible in the socket for closing the circuit through the batteries, telephone and lamp, and means for Winding the cable on the drum.

In testimony whereof, I afiix my signature, in the presence of two Witnesses.
